Classification

Originators of correspondence, communications, equipment, or documents within
the Agency are responsible for ensuring that the proper classification,
downgrading information and, when appropriate, proper caveat notations are
assigned to such material. (This includes any handwritten notes which contain
classifiedinformation). The three levels of classification are Confidential,
Secret and Top Secret. The NSA Classification Manual should be used as
guidance in determining proper classification. If after review of this document
you need assistance, contact the Classification Advisory Officer (CAO) assigned
to your organization, or the Information Policy Division (Q43).
